A consistent SIR model on time scales with exact solution

Márcia Lemos-Silva, Sandra Vaz, Delfim F. M. Torres

We propose a new dynamic SIR model that, in contrast with the available model on time scales, is biological relevant. For the new SIR model we obtain an explicit solution, we prove…

The Omega Calculus of Variations

Márcia Lemos-Silva, Delfim F. M. Torres

We prove a necessary optimality condition of Euler--Lagrange type for the calculus of variations with Omega derivatives, which turns out to be sufficient under jointly convexity of…
